Data from: Quantitative plant taphonomy: the cosmopolitan Mesozoic fern Weichselia reticulata as a case study
<p>A quantitative approach to plant taphonomy focusing on preservation type and fragment size is tested by comparing 3338 <em>Weichselia reticulata </em>fragments from 25 Lower Cretaceous localities of different ages and depositional environments. Moreover, palaeobiological insights are also obtained from the taphonomic analyses. In the case of the specimens of <em>Weichselia reticulata</em> included in this work, charred remains are the most frequent preservation type. They are the smallest and most homogeneous in size, probably due to the fragmentation of the fronds while burning and to the fact that burnt fragments are more fragile and break easily during the initial abrasion and attrition produced by transport. The sizes of charred fragments vary depending on the depositional environment, suggesting that biostratinomic processes, and not fire temperature, are the main cause for size differences, and providing valuable insight into the distance the remains might have traveled from production to final deposition. The taphonomic analyses suggest that <em>Weichselia reticulata</em> is allochthonous in all the localities analysed, and that its habitat would have been prone to fire and not far from freshwater systems. This case study shows promising results that can be implemented on different plant groups and chronostratigraphic ages, allowing for the proposal of a taphonomic model.</p>

Weichselia Mantelli Tree Fern Fossil
Cretaceous period tree-fern Weichselia mantelli (one of several Wealden species named after Gideon Mantell) from the Tunbridge Wells Sand, excavated from Mountfield Road, Tunbridge Wells, UK, in 1895. Digital asset created as part of the 'A Mirror For Remembering' artwork commission by Alex May: http://amirrorforremembering.com/ A Mirror for Remembering is a major new virtual reality artwork by Alex May exploring the complexities and growing necessity to address the preservation and permanence of the digital artefacts that form an increasing part of our everyday lives. This commission has been made possible through the generous support of the Arts Council England funded Kent Medway Museums National Portfolio Organisation and tilises the extensive collections held by Tunbridge Wells Borough Council.
